WEDNESDAY, April 25 (HealthDay News) -- So, what
does the "G" stand for in G-spot? Maybe it's "G" as in Holy
Grail, because a Florida gynecologist contends that he has finally
By means of a seven-hour dissection, Dr. Adam Ostrzenski said,
he located the elusive source of female sexual satisfaction deep
within the vagina. He makes his claim in a paper published online
April 25 in
The Journal of Sexual Medicine.
But several experts are highly skeptical of Ostrzenski's
assertion, saying his paper is long on speculation and
headline-grabbing potential and short on proven scientific
Ostrzenski, director of the Institute of Gynecology in St.
Petersburg, said he performed the layer-by-layer vaginal dissection
on the cadaver of an 83-year-old woman who had just died of head
The existence of the G-spot is a matter of intense debate. It
was actually named after scientist Ernest Grafenberg, author of the
landmark 1950 article, "The Role of Urethra in Female Orgasm."
Part of the controversy is that -- unlike the clitoris -- the
G-spot has never been seen or felt as a distinct structure.
Although many women have reported sexual pleasure stemming from the
anterior (frontal) part of the vagina, nobody could document a more
precise source or describe its size and appearance.
Ostrzenski said the structure uncovered in the study had three
distinct sections, sat at a 35-degree angle inside the urethra, and
"has a bluish, grape-like appearance."
He said he plans to perform similar forensics on the bodies of
women of various ages.
If Ostrzenski and others can consistently reproduce the
discovery, he said, "it may absolutely change our view of how the
orgasm is created; it will change the understanding of sexual
function. It may help in the treatment of the dysfunctional aspect
Not so fast, cautioned one of three experts who strongly
criticized the study.
Barry Komisaruk, a distinguished professor in the department of
psychology and associate dean of the graduate school at Rutgers
University, submitted the trio's concerns in a journal
Komisaruk, a behavioral neuroscientist, said the study author
made vastly unwarranted conclusions from a single tissue sample
without performing appropriate scientific tests. For all anyone
knows, he said, rather than locating the G-spot, Ostrzenski may
have found a sign of disease, such as a tumor.
The study also lacked "microscopic analysis to determine if it
is glandular or erectile tissue, whether the 'vessel' is a blood
vessel or a secretory duct, whether the tissue has a nerve supply,
and whether it is normal or pathological tissue," Komisaruk
"We submit that the author's claim to have discovered 'the' G-spot does not fulfill the most fundamental scientific criteria," wrote Komisaruk and his co-authors.
For claims to be taken seriously, he said, they must be backed
by "dissections using microscopic and chemical analysis, in women
of all ages. Not only dissections, but observations of this body
region in life, using modern imaging and other methodologies,
correlating with those who do or do not claim to have a 'G-spot,'"
along with other research.
Study author Ostrzenski said he could only speculate as to why
nobody had made the discovery before him. "The location of the
G-spot is quite deeply situated and maybe that is the reason," he
said. "The second aspect is that the vagina exists in separate
layers and surgery is usually performed on the upper part."
Besides his own work, Ostrzenski said that genetic findings,
studies of vaginal electrical activity and centuries of
descriptions from women support the G-spot's existence.
